OIL-PRESS.

SPECIFICATION forming part of Letters Patent No. 543,343, dated July 23, 1895.

Application filed July 7, 1894. serial No. 516,852. (No model.)

To'aZZ whom it may concern.-

Be it known that I, JULIUS KOCH, a subject of the German Emperor, residing at Miinden, Germany, have invented certain new and useful Improvements in Oil-Presses, of which the following is a specification. 1

. This invention relates to an improved oilpress, in which the oil-seed is divided by a series of press-plates, which are automatically introduced into the straining-vessel, so -that alternate layers ofoil-seed and press-plates are formed.

' sel.

In the accompanying drawings, Figure 1 is a plan of the plant. Figs. 2, 4, and 6 are vertical sections of the oil-press, showing the parts in different positions. Figs. 3, 5, and 7 are plans of Figs. 2, 4, and 6, respectively. Fig. 8 is a'section through the straining-ves- Figs. 9 and 10 are cross-sections of Fig. 8. Figs. 11, 12, and 13 are detail verticalsections and an elevation of the straining-vessel.

The letter A represents the straining-vessel, adapted to be moved along rails s, which form a track between the feed-vessel and the press apparatus. The oil-cakes are separated within the straining-vessel by plates 1), which are automatically introduced after one ansel.

other and are covered with the desired quan tity of oil-seed, after which they are released to fall upon a desceriding'piston.

The plates 19 are stored within a receptacle (1, which is arranged above the strainingves- This receptacle is mounted upon a table h, upon which the oil-seed box is and the arms 0, which are connected thereto, may be recip rocated by crank-rods d. The receptacle a is provided with a slit s above its bottom and opposite to the straining-vessel A, so that one plate may be slid outward at a time. The withdrawal of the plates is efiected by the arms 0, turning on pivots q and adapted to be thrown outward against stops 6 by springs fi During the forward motion the arms 0 clear the plates 10, while during the backward motion they are pressed against the lowermost plate and encircle the same with their curved ends. These ends are provided with the pawls g, which come into contact with guide-rails 2' during the forward and also during the backward motion, and which are thus revolved as far as stops g 9 will permit. During the forward motion the pawls will assume the position shown in Fig. 5, and the arms will be spread by their springs f, so as to clear the platesp; but during the backward motion the pawls will'strike the front ends of the rails 1' and will assume the position shown in Fig. '7, so that the arms 0 will be moved toward each other and will engage the lowermost plate 19. In this way such plate will be taken along until it arrives over the straining-vessel, when it will be released, because the pawls g will now clear the rails 71 and the arms 0 will be spread by the springs f. The plate 10 will now fall through an opening of the table 72. and upon the fingers m of the straining-vessel. The feed-box It will next arrive beneath then by crank-rod d moved toaposition above the opening of the table h to permit the oilseed to drop into the straining-vessel. In order to spread the seed uniformly uponthe plate 1) the box is moved across the entire opening of the table before it recedes. The fingers m, upon which the plates p rest, are movably secured to a ring a" and reach into the interior of the straining-vessel through slits m. The ring 7' is retained by springnin the position shown in Fig. 9, in which the lingers m strike againstthe edget of openmg 00 and are thus moved inward. During the backward motion of the oil-box k and arms 0 a stop 6, depending from box 70, will strike against a lever to to revolve ring r, and to thus cause the fingers m to strike against the edge t of opening w. Thus the fingers will be withdrawn and the first plate 19 will be free to drop upon the piston y. The piston y is moved slowly downward, the motion being imparted either separately or in connection with the slide-box.

After the straining-vessel is filled in the manner described, it is placed into a'press and the piston,upon which the seed-cakes have previously descended, will rise, so that the pressed residue as well as the plates may be separately removed at the top.

In lieu of storing the plates 10 in a receptacle above the table theymay be stored in a receptacle below the table, in which case they the oil-seed tank (heater) 0 to be filled.- It is I are raised by mechanical or hydraulic means,

so that one plate is elevated at a time, drawn toward the straining-vessel by the arms a and placed upon the fingers m in the manner already described.

What I claim isl. The combination of a straining vessel A, with a reciprocating feed box 70, arms 0, having pawls g, plate storing receptacle a, rails 1', adapted to engage the pawls, and means for opgrating the arms- 0 substantially as specifie 2. The combination of a straining vessel with a ring 7', above the same fingers m, pivoted thereto, and with a reciprocating feed box having a stop that is adapted to engage
